SHUTTLE-CHECK FOR LOO WlS-fl Specification of Letters Patent.

Patented April 17, 1906.

Application filed July 12, 1905- Serial No. 269,298.

To all whom it may concern.-

Be itknown that I, JEAN LAFoRnT, a citiz en of the Republic of France, residing at Etoile, in the Department de la Drome, France, have invented certain new and useful Improvements in Shuttle-Checks for Looms; and I do hereby declare the following to be. a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to shuttle-checks for looms; and it has reference particularly to that class of such devices wherein the binder or movable part of the box is a contrivance which comes to bear against the shuttle at two different points thereon as the shuttle is driven home.

One of the principal objects of the invention is to provide a shuttle-check which acts to bring'the shuttle gradually to a stop as it enters the box and at the same time prevent rebound thereof.

To this end my invention consists of a shuttle-check comprising a primary lever engageable with the shuttle and another or secondary lever adapted at one end to press the primary lever inwardly and having its other end projecting into the path of movement of and adapted to be engaged by the shuttle, whereby said secondary lever acts to effect inward pressure on the primary lever when the shuttle is about completely home.

Referring to the accompanying drawings, Figures 1 and 2 are plan views of a shuttlebox provided with my improved shuttlecheck, showing the parts thereof in two dif ferent positions, the one where the shuttle is out of the box and the other where it is in the box; and Fig. 3 is a rear view of the shuttlebox shown in Figs. 1 and 2.

In the accompanying drawings, a is the lay or batten, b a shuttle-box on one end thereof, having front and rear walls 0 and d, and e the picker-stick, which works in a slot f in the bottom of the box and actuates the picker all according to the usual construction.

In the back wall (1 of. the box is formed an opening it, which near one end (preferably the end toward the adjacent end of the batten) is penetrated by a vertical pin t', which forms the fulcrum for a lever j, which has a long curved wearing-face k, with which the shuttle engages and which bears against the middle portion of the shuttle. To limit the inward movement of lever it is formed with an extension Z, adapted to be received by a rabbet m in the adjacent end of the opening It.

On the back of the box above opening h is secured, as by screws n, a bracket 0. p is a lever carried by a bracket q, (to which it is secured by bolts 13) which is fulcrumed on a pin 8, mounted in bracket 0 and held therein by a nut t screwed onto the pin. Lever p has the end thereof toward the adjacent end of the box bent first inwardly and then toward said adjacent end of the box, the latter or extremity portion thereof forming a shoe u and preferably having a relatively broad face with which the shuttle contacts, the inbent portion of said lever extending through an opening o, formed in lever j, The other end of lever 19 is about parallel with lever and it carries secured therein by nuts w a screw at, whose head is adapted to bear against a platespring 'y, secured against the back of the lever by screws 2.

1 is a spring which has one end, as at 2, bent over the inner end of lever and its other end coiled about pin 8 and firm y secured against bracket 0 by nut t. This spring normally presses the inner end of lever p toward lever and so keeps the latter in-pressed.

When the shuttle enters the box, it first presses lever j outwardly and then engages the shoe u of lever p, thereby pivotally moving said lever p and causing the screw as to press against spring y, and so force lever 7' against the side of the shuttle. It will be observed that since lever j engages the middle portion of the shuttle, as above described, it securely clamps the same and prevents rebound. When the shuttle leaves the box, the pressure of the two levers is of course continued until the shuttle clears the shoe 0,, whereupon, the latter being free to move inwardly and the lever 1' free to move outwardly, the pressure ceases.

Having thus fully described my invention, what I claim, and desire to secure by. Letters Patent of the United States, is

1. The combination of a shuttle-box and a shuttle-check comprising a primary lever, a

shuttle-check comprising a primary lever and a secondary lever fulcrumed in said box, said primary lever having one end en ageable by the shuttle and said secondary lever being fulcrumed between its ends, having one end engageable with the shuttle-engaging end of said primary lever and having the other end thereof projecting into the path of movement of the shuttle, said secondary lever comprising an adjustable device forming the part directly engageable with the substantially as described.

.3. The combination of a shuttle-box and a shuttle-check comprising a primary lever, a secondary lever fulcrumed in said box, said primary lever havi g one end engageable by the shuttle and said secondary lever being fulerumed between its ends, having one end engaging the shuttle-engagin end of said primary lever, and having its ot er end projecting into the path of movement of the shuttle, and a spring pressing the secondary lever against the primary lever, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of May, 1905.
